• Sampling rate: 240 per second
• Architecture: Sigma-Delta
• Data interface: SPI
• Configuration: MUX-ADC
• Number of A/D converters: 1
• Reference type: External
• Supply voltage ranges: 2.7V ~ 5.5V (both analog and digital)
• Temperature sensor feature
• Operating temperature range: -40°C ~ 85°C
• Package: 14-TSSOP
• Mounting type: Surface Mount

All substitute parts listed maintain identical electrical specifications and mechanical compatibility with the original ADS1222IPWRG4. Differences exist only in packaging format and product availability status.

Parameter Comparison

Engineering Selection Recommendations

ADS1222IPWR is the manufacturer-recommended substitute. This part maintains full electrical and mechanical equivalence to the ADS1222IPWRG4 while offering active product status and availability in Cut Tape (CT) and Digi-Reel® packaging formats. Current inventory of 4,100 units supports production requirements.

ADS1222IPWT is a parametric equivalent offering identical electrical specifications and mechanical compatibility. This variant provides the highest inventory availability at 59,050 units and is actively supported by the manufacturer. Both substitute parts carry ROHS3 compliance and REACH unaffected status, matching the original part's regulatory certifications.

Selection between ADS1222IPWR and ADS1222IPWT should be based on packaging requirements and supply chain logistics. Both parts are functionally interchangeable with the discontinued ADS1222IPWRG4 for all data acquisition applications requiring 24-bit Sigma-Delta conversion with external reference and SPI interface.

Frequently Asked Questions (FAQ)

Q: Can ADS1222IPWR and ADS1222IPWT be used interchangeably with ADS1222IPWRG4?

A: Yes. Both substitute parts maintain identical electrical specifications, pin configuration, and mechanical dimensions. The 14-TSSOP package and surface-mount footprint are identical across all three part numbers. No circuit modifications are required for substitution.

Q: What is the difference between ADS1222IPWR and ADS1222IPWT?

A: Both parts are electrically and mechanically equivalent. The primary difference is packaging format: ADS1222IPWR is supplied in Cut Tape (CT) and Digi-Reel® format, while ADS1222IPWT uses the same packaging options. Inventory levels differ, with ADS1222IPWT offering significantly higher stock availability.

Q: Are there any compliance or certification differences between the substitute parts and the original ADS1222IPWRG4?

A: No. All three parts carry identical ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 2 (1 Year) ratings. Regulatory and environmental certifications are equivalent across all variants.

Q: What is the significance of the product status change from discontinued to active?

A: The substitute parts (ADS1222IPWR and ADS1222IPWT) are actively manufactured and supported by Texas Instruments, ensuring long-term availability and supply chain continuity. The original ADS1222IPWRG4 has been discontinued at DiGi Electronics, making substitution necessary for ongoing production.

Q: Are there any performance differences in data acquisition between these parts?

A: No. All parts feature identical 24-bit resolution, 240 samples-per-second sampling rate, Sigma-Delta architecture, and external reference configuration. Functional performance in data acquisition applications is equivalent.

Q: Can existing PCB designs accommodate these substitute parts without modification?

A: Yes. The 14-TSSOP package dimensions (0.173" width, 4.40mm) and surface-mount footprint are identical. Existing PCB layouts and assembly processes require no changes for component substitution.
